1. In the Gram Stain procedure, which component acts as the mordant?

Correct answer: C

Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.

2. A home health nurse is preparing to visit her next client, whom she has never visited before. Which of the following actions indicates the nurse is upholding safety precautions?

Correct answer: D

Rationale: The correct answer is to keep the car windows rolled up when in an unfamiliar environment. This action helps uphold safety precautions for the home health nurse. When visiting a new client in an unfamiliar area, it is essential to ensure personal safety. Keeping the car windows rolled up can prevent potential intruders or unwanted individuals from gaining access to the nurse while in the vehicle. This precaution is important for personal safety and security. Choice A, sending a text to the client to confirm the location of the house, is not directly related to the nurse's safety during the visit. While communication with the client is important, it does not directly address the nurse's safety. Choice B, leaving her purse and valuables on the seat in the car, poses a security risk. It is not advisable to leave valuables visible in the car, as it may attract thieves and compromise the nurse's safety. Choice C, asking the client to keep an extra set of keys, is more related to accessibility and convenience rather than the nurse's safety. While having an extra set of keys may be helpful, it does not directly address safety precautions for the nurse.

3. Your patient who had AIDS/HIV has just died. Should you still use standard precautions as you provide post-mortem care?

Correct answer: A

Rationale: Yes, you should still use standard precautions even after an HIV/AIDS patient has died. The virus can remain infectious after death, and healthcare workers need to protect themselves from potential exposure. Choice B is incorrect because while respect is important, the primary reason for using standard precautions is to prevent transmission of infectious diseases. Choice C is incorrect as the virus can still be transmissible even after the patient's death. Choice D is incorrect as using standard precautions is a matter of infection control, not a question of respect.

4. A patient works with a nurse to establish outcomes. The nurse believes that one outcome suggested by the patient is not in the patient's best interest. What is the nurse's best action?

Correct answer: C

Rationale: In this scenario, the nurse should collaborate with the patient rather than impose personal opinions. While the nurse should respect the patient's autonomy, they also have a duty to provide guidance. By exploring possible consequences of the suggested outcome with the patient, the nurse can facilitate a discussion that helps the patient make an informed decision. This approach respects the patient's input while ensuring their well-being. Remaining silent (Choice A) may not address the issue, educating the patient unilaterally (Choice B) may be perceived as dismissive, and formulating an outcome without patient input (Choice D) disregards the patient's autonomy and preferences.

5. What is the best outcome for a patient with the nursing diagnosis: Impaired social interaction related to sociocultural dissonance, as evidenced by stating, "Although I'd like to, I don't join in because I don't speak the language very well?"? The patient will:

Correct answer: D

Rationale: The correct outcome for the patient with impaired social interaction related to sociocultural dissonance is to select and participate in one group activity per day. This outcome focuses on increasing social involvement, which aligns with addressing the nursing diagnosis. The patient has already expressed a desire to interact with others, so the goal is to facilitate actual participation in social activities. Becoming more independent in decision-making and demonstrating improved social skills are not directly related to the specific nursing diagnosis provided. Additionally, the outcomes must be measurable, making choices A and C less appropriate as they lack specificity and measurability.
